Table-leaf support



UNITED STATES PATENT PETER s. CRAWFORD, or ROGKFORD, ILLINOIS.

TABLE-LEAF SUPPORT.

SPECIFICATION forming part of Letters Patent No. 249,312, dated November8, 1881.

Application filed May 19, 1881.

To all 'whom 'it may concern Beit known that LPETER S. CRAWFORD, acitizenlof the United States, residing at Rockford, in the county ofWinnebago and State of Illinois, have invented certain new and usefulImprovements in Supports for Table-Leaves; and I do hereby declare thefollowing to be a Y yfull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying l drawings, andto the letters or figures of referencemarked thereon, which form a part of this specification. Y j

The object of this invention is to simplify the device for supportingthe leaves of tables, and at the same timehave the table-leaf,whenraised up and supported, secure against any j danger of beingaccidentally made [to drop,

and thereby break what may beupon it; and it consists in theconstruction of theparts forming the device, as will be fully,hereinafter` described.

In the drawings, Figure l represents the underside view of a table-leafwhen raised and the `device in position to support the leaf. Fig. 2represents a side view, partly in section, on line a.' ,fr of Fig. 1.Fig. 3 represents a transverse broken sectional view ot' Fig. 1 on liney y, and Fig. et represents the upper side ofthe tilting catch.

A represents the frame of a common fallleaf table.

B represents the bed, resting on frame A.

C represents the fall-leaf as hinged in the usual manner to bed B.

D represents the hinged holding-brace or support, and hinged at d toframe A, and has projecting lugs d near its outer end on opposite sides,the forward faces of which are at, or nearly at, right angles with theunder side of lip df, at the extreme outer end of brace D, as seen inFig. 2, at d".

. E is a slotted guideway, screwed fast to the under side of thetable-leaf by the screws e and e.

E shows the longitudinal. slot in the under side of the guideway, and atthe outer end there is a narrower slot, e, in which the hold- 5oing-screw e is inserted, to hold the outer end (Model.)

of the guideway fast to the leaf, and while it so holds the guidewayfirmly to the leaf, and the wood is not thoroughly seasoned, will allowthe wood to contract without in any way disturbing the relative positionof the guideway with the brace-support, which is free to have its outerend slide in the guideway.

- f f are inwardlyjprojecting anges on the under face ofthe guideway,and on each side of the longitudinal slot E', the office of which is tokeep the outer end of the brace D, by its projecting lugs d' ,fromfalling out of the guidewayin its reciprocations in raising or droppingthe leaf, as seen in Fig. 3.

Gr is a tilting catch, and acts to catch the end of the brace and holdit rm when the leafl C is raised to be on the same plane with the bed ofthe table. It is slotted to fit transverse# ly in openings in the sidesof the guideway E, as seen in Fig. 1, the parts g and g"`project ing onopposite sides thereof.

g is a rounded projection on catch G, on the side next the table-leaf,forming a kind of fult crum to the catch, and upon whichit tilts, thebearingsin the openin gsin the sides ofthe guideway beingsuch that theouter points of theopenings `will always bear upon the outer edges ofthe part-s g and g, while the inner parts ofthe openings are deeper,which cause the inner edge of the catch to freely recede from thetable-leaf when free, and when the brace-support, with its outer endconstructed as described and shown, is inserted in the guideway, and theguideway and the brace-support firmly attached to the parts of thetable, and the leaf is raised, as seen in Fig. 2, the brace will havepassed over the inner edge of the catch, pressing it down as it passed,and as soon as relieved from such pressure the edge ofthe catch springsaway from the table-leaf before the abutting part of the brace-supportand locks the bracesupport firm in position to hold the leaf on a planeWith-the bed B.

To release the catch and let the leaf C fall by its own weight, pressthe thumb part g' of catch G until it tilts out of contact with theouter end of the support D, when the leaf is free to swing on its hingesand fall into an up right position. By simply raising the leaf the I layno broad claim to a slotted gnideway In testimonyT whereof I affix mysignature [o or to a brace-support guided by a guidewayin in presence oftwo Witnesses. its operations to support a table-leaf; but

What I do claim as my invention is- PETER S. URAVFORD. 5 The rocking ortilting catch G, having the fulcrum-projection g and projecting thumbWitnesses: part y', in combination with the gnidewzty E R. F. CRAWFORD,and support D, constructed substantially as J. B. CRAWFORD. and forthepurposes described.
